A large, slow-walking robot is after a guy who has something the robot wants (or he’s after the guy). The robot doesn’t walk around homes or buildings to get to him, but leaves a path of destruction by walking through them, killing people along the way. No matter where the guy goes, the robot will follow.
JUMP TO THE END:
The solution to keep everyone safe is the authorities used a large warehouse and lured the robot to it. A camper, loaded with everything you need to live, had the guy (or the item) in the camper. Because the robot walked so slowly, they were able to drive in a circle and the robot followed forever.
